In Chazal's day, fewer animals were fed artificial mixes, and no one
farmed in such bulk, so it was very rare. But in their day, DA would
simply have killed the cow. What makes them baalos mum is the surgery
now performed to save them. The question is new because the metzi'us
is new.

As for bitul beshishim... I haven't caught up to Avodah, and since I
moderate, I know how many relevant posts I didn't read for content.
BUT, I still fail to see the assumption this is a bitul issue.

We recently discussed the machloqes the Rashba and the Rash about a
ta'aroves that includes a mi'ut de'ikka leqaman of cheilev. Three
pieces of fat, two shuman, one cheilev. We don't know which is which,
in a manner that no chatichah is qavu'ah. All may be eaten. But once
mixed as a ta'aroves, the Rosh assurs.

So, according to the Rashba, it should be a simple case of rov, not
bitul beshishim. The ta'aroves doesn't change that. Once we can say
rov cows aren't tereifos, the milk is kosher.

But for the Rash... Here it's more complicated, since the mi'ut of
tereifos are a ruba deleisa leqaman -- it's only statistically that we
say there is bound to be a mi'ut of chalav tereifah. It's not a usual
ta'aroves of known quantities. Can we say bitul beshishim when it's a
ta'aroves whose 1/60 is determined statistically?

Are we even chosheshim for the Rash in such a case?

Tir'u baTov!
